Three Phase Electrical Calibration Equipment Programmable Standard Power Source

Three Phase Electrical Calibration Equipment Programmable Standard Power Source

1 Overview

The XL-803 three-phase programmable standard power source is a new generation of high-precision standard power source based on 1.2 G MAC DSP, large-scale FPGA, high-speed and high-precision DA and high-fidelity power amplifier. Applicable to electric power system, electric power, remote control, dispatching and other power departments and enterprises that need measurement, inspection and high-precision standard signal sources. It is also suitable for other occasions where high-precision standard signal sources are required for measurement and inspection.
XL-803 can output high-precision voltage and current with adjustable frequency, phase and amplitude at power frequency (40Hz~65Hz). It is a highly accurate adjustable voltage and current standard source. The XL-803 can output very pure sinusoidal voltage current with a distortion of no more than 0.1%, typically 0.03%. The XL-803's voltage and current outputs have very high output stability, typically 0.004% RD. Therefore, it is very suitable for work situations requiring high-precision inspection and calibration, such as the measurement department for the detection of various voltage, current, power and other electrical parameter meters.

Main features and functions

1. Main features
1) It is possible to output a pure sinusoidal power signal with a distortion of 0.03% (typical).
2) Each harmonic output can be superimposed on the fundamental wave.
3) The frequency output can be adjusted from 40Hz to 65Hz, the resolution is 0.002Hz, and the accuracy is 0.002Hz.
4) The AB phase is a frequency reference, and the C phase is a separate frequency reference, so it can be phase-separated.
5) The phase 0~360 degrees can be adjusted arbitrarily, which can easily simulate various power supply situations and even reverse power transmission.
6) Strong load capacity, can carry capacitive, inductive, resistive load or composite type load, and the load regulation rate is better than 0.01% RG.
7) Excellent temperature stability, the core device is a military grade product with a temperature coefficient as small as 1PPM, which can guarantee the output precision in the outdoor temperature environment.
8) It is powerful and flexible with 32-bit MCU+DSP processor.
9) The waveform of the power frequency is up to 50,000 points per week, and the internal signal output does not need a filter for smooth filtering, which ensures the accurate output of the waveform, so that the system can output accurate harmonics, and the system has excellent harmonic distortion. index.
10) It can be easily connected to the PC through an RS232 to expand other functions.
11) Perfect overcurrent, overvoltage, overheat, short circuit, open circuit, overload protection.
12) Hardware PID, the response is extremely fast, and the change of load will not cause the fluctuation of the output.
13) 320*240 liquid crystal display, Chinese interface, easy to operate.
14) Open communication protocol to facilitate secondary development (factory automatic verification of RTU/FTU/power management terminal/common measurement terminal).
15) It can be loaded with pure capacitive load, and the power meter can be checked with PC software.
